GENERAL KNOWLEDGE

Detailed explanation-1: -Cleavage-The tendency of a mineral to break along flat planar surfaces as determined by the structure of its crystal lattice. These two-dimensional surfaces are known as cleavage planes and are caused by the alignment of weaker bonds between atoms in the crystal lattice.

Detailed explanation-2: -Cleavage and Fracture If a mineral contains weaker chemical bonds that are aligned, then these minerals will break along the planes of weakness created by these weaker chemical bonds. The ability of a mineral to break along smooth planes of weakness is a physical property called mineral cleavage (or just cleavage).

Detailed explanation-3: -Cleavage. is the tendency of a mineral to break along flat surfaces. The way in which a mineral breaks depends on how its atoms are bonded, or joined together. In a mineral that displays cleavage, the bonds of the crystal structure are weaker in the directions in which the mineral breaks.
